A game played by a group of friends who like drinking too much. An unlimited amount of players can take part but it is usually recommended that under 10 do. Every player has one metaphorical 'wildcard' which they can play at any time they like. They send out their wildcard by text whenever they like giving 2 hours notice with a time, a place, and a fancy dress.
